Verification Protocol

Stress Test

Sustained GPU load via a hand-written Vulkan compute kernel

Duration: 5m 00s
Dispatches: 2,134
Peak temperature: 80°C
Thermal stability: Stable

VRAM Pattern Test

Bit-pattern write/verify sweep across active memory

Duration: 10m 00s
Coverage: 3.1 GB (77%)
Passes run: 6,878
Errors: 0

Render Integrity Test

Deterministic graphics-pipeline render, checked pixel-for-pixel against the expected output, catches rasterizer/shader-core defects the compute and VRAM tests can't see

Duration: 0m 45s
Frames rendered: 10,490
Pixels checked: 687,472,640
Mismatches: 0
